Wood-fiberglass hybrid panel door

ABSTRACT

A wood-fiberglass hybrid panel door featuring natural wood veneer permanently bonded to at least one side of a fiberglass door. The panel and the stile/rail portions of the fiberglass door skin for bonding wood veneers can be either one-piece compression molded construction or can be separately compression molded pieces joined together by mechanical or chemical methods. The two pieces of door skins are used to make a fiberglass door first. Wood veneer is then bonded to at least one side of the said fiberglass door through the use of a vacuum press. Wood raised molding or flush sticking is applied around the veneered panel to cover the veneer edges on the panel and/or stiles/rails. Wood raised molding or flush sticking is fixed to the door by mechanical or chemical methods.

RELATED APPLICATION

This application is a continuation application of China Patent Application No. 201210128176.7, filed on Apr. 28, 2012 in the China Intellectual Property Office.

FIELD OF INVENTION

The present invention relates to the construction industry, particularly a wood-fiberglass hybrid panel entry door featuring natural wood veneer permanently bonded to a fiberglass panel door.

BACKGROUND OF THE INVENTION

Wood entry doors are popular because of their natural beauty, but they are not energy efficient and will warp, swell and rot over time. Fiberglass doors are very durable and energy efficient, but they lack the warmth and beauty of natural wood.

SUMMARY OF THE INVENTION

The object of this invention is to provide an entry door that combines the best of both wood and fiberglass doors, i.e., the beauty of natural wood doors and the durability and energy efficiency of fiberglass doors. The structure of the present invention is used in conjunction with a fiberglass panel door. The natural wood veneer is bonded to at least one side of the door. The fiberglass panel door is constructed of stiles/rails and at least one panel.

The panel and the stile/rail portions of the fiberglass door skin can be either one-piece compression molded construction or separately compression molded pieces joined together by mechanical or chemical methods. The natural wood veneer is individually bonded to the surfaces of the fiberglass door panel portion and the stile and rail portion. Decorative solid wood molding or sticking is then applied around the panel to cover the edges of the veneers bonded to the panel portion and the stile and rail portion, making the veneered fiberglass panel door look just like a natural wood door.
